PROBLEM TO BE SOLVED: To obtain a halogen-free olefin-based resin composition satisfying, well in balance, such properties as an abrasion resistance, flame-retardant, tensile property, flexibility, thermostability and cold resistance that are required for covered materials of electric wires for automobiles. SOLUTION: The olefin-based resin composition is composed of (a) 50-80 pts.wt., propylene polymer, (b) 10-40 pts.wt. thermoplastic resin having a melting point of 130 deg.C or above and a Shore's A hardness of 90 or below, (c) 1-20 pts.wt. polyolefin denatured by an acid anhydride of 0.1-10 wt.% (wherein the total of the polymers (a), (b) and (c) is 100 pts.wt.), and (d) 30-200 pts.wt. of a metal hydroxide. |
